FOR SALE: Nauticam Macro Port 87 (Nikon 105 VR, Canon EF 100 USM)

This is an essentially brand new Nauticam macro port. It has been on only one dive trip and has no scratches or marks anywhere. I am selling simply because I shoot mostly with the 60 mm macro and rarely use my 105 mm lens. I've switched to a Nauticam Macro port 60 that I use with an extension ring whenever I shoot my 105 mm.

The port was purchased new from Reef Photo for $400. I would like to see it for $300.
